The windshield wipers only worked occasionally. ... My 1998 dodge ram wipers only work on high will this help me? thanks.... Express van. you have to take out the motor and the transmission from under the front of the van..

The rear wiper has its own pump motor. pull the hose from the wiper and have someone engage to see if there is a clog. do the same at the motor. if bo liquid comes out then its the pump. also check fluid level in reservoir as well as a possible secondary reservoir

Check wiper fuse. If ok turn key to on position and try to pull wiper arm into the direction that they would swipe on the windshield. If this doesn't work u could try tapping on the wiper motor while the key is on to see if that works. Use a test light to see if motor has power to it.

why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?

What happens when you activate the washers?

go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.

don't have 1983 info, but here is 1994:
